Description

when i view and study the source code of the rocketmq.
i find some problems code.
In the NamesrvStartup class, i find when the commandLine.hasOption('p') that the next code is
make no difference:

if (commandLine.hasOption('p')) {
         //the code below have no no difference,because the first arg is null. the printObjectProperties method will do nothing when first arg is null.
                MixAll.printObjectProperties(null, namesrvConfig);
                MixAll.printObjectProperties(null, nettyServerConfig);
                System.exit(0);
            }

如果参数含有-p的话，走入这个分支，但是MixAll.printObjectProperties()方法内部实现，如果第一个log参数是null的话，不会做任何事情，是不是应该把配置参数打印在控制台上
